高中英语非限定性定语从句语法归纳

非限定性定语从句是英语语法中从句的一种,是定语从句的分支之一。作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立。运用非限定性定语从句,尤其要注意其语法运用及其所表示的东西。 1 who引导的非限制性定语从句 Our guide,who was a French Canadian,was an excellent cook. 我们的向导,一个法裔加拿大人,擅长于烹调。 My gardener,who is very pessimistic,says that there will be no apples this year. 我家的园丁非常悲观,他说今年将不结苹果。 2 whom引导的非限制性定语从句。 关系代词whom用于指人,在句中作动词宾语和介词宾语,作介词宾语时,介词可位于句末。 如:Peter, whom you met in London, is now back in Paris. 彼得现在回巴黎了,你在伦敦见过他。 Mr Smith,from whom I have learned a lot,is a famous scientist. 史密斯先生是一位著名的科学家,我从他那儿学了许多东西。 3 whose引导的非限制性定语从句。 whose是关系代词who的所有格形式,在从句中作定语。whose通常指人,也可指动物或无生命的事物。 如:The boy, whose father is an engineer, studies very hard. 那位小男孩学习很努力,他的父亲是位工程师。 Above the trees are the mountains, whose magnificence the river faithfully reflects on the surface. 在树林的高处是山,其壮丽的景色完全映照在河面上。 The play,whose style is rigidly formal,is typical of the period. 这剧本是那个时期的典型作品,风格拘谨刻板。 4 which引导的非限制性定语从句。 关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句,在从句中作主语、动词宾语、介词宾语或表语。 ①which指代主句中的名词,被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。 如:These apple trees,which I planted three years ago,have not borne any fruit. 这些苹果树是我三年前栽的,还没有结过果实。 She is an artist,which I am not. 她是一位艺术家,而我不是。 Water,which is a clear liquid,has many uses. 水是一种清澈的液体,有许多用途。 The two policemen were completely trusted,which in fact they were. 那两个警察完全受到信任,事实上,也真是如此。 ②which指代主句中的形容词。 如:She was very patient towards the children,which her husband seldom was. 她对孩子们很耐心,她丈夫却很少这样。 She is always careless,which we should not be. 她总是马虎大意,我们可不应该这样。 ③which指代主句中的某个从句。

定语从句常见考点

解题思路 1.通读全句。首先判断是什么句型。 2.题干句如果是疑问句式,将其转化为陈述句式。 3.分析从句的句子结构,在定语从句中,缺什么,就补什么:缺主或宾语,用关系代 词;缺状语,用关系副词 4. 注意标点符号和题干中是否存在并列连词and, but等。 常见考点 1.指物时只用that 或which 的情况 2.介词+关系代词 3.Whose 用法及转换形式 4.as 与which的区别 5.指人时that 与who的区别 6.如何判断用关系副词还是关系代词 7.定语从句中的主谓一致问题 1. This is all ____ I know about the matter. A. that B. what C. who D. whether 2. Is there anything else _____ you require? A. which B. that C. who D. what 3. The last place _____ we visited was the Great Wall. A. which B. that C. where D. it 4. He talked happily about the men and books _____ interested him greatly in the school. A. which B. that C. it D. whom 5. There is no dictionary _____ you can find everything. A. that B. which C. where D. in that 6. Is oxygen the only gas _____ helps fire burn? A. that B. / C. which D. it 7. Which was the hotel _____ was recommended to you? A. that B. which C. where D. it 考点一:that 与which 的区别 1. 先行词为all, little, much, everything, nothing, something, anything等不定代词 2.先行词被all, little, much, every, no, 等修饰时 .3先行词被序数词或最高级修饰先行词前有序数词(the first),形容词最高级(the best), the last, the very, the only 等时。 4. 先行词为人和物的组合 5.若主句中有疑问代词who 或者which,为了避免重复, 关系代词不要再用who, which,而用that。 考点二:介词+关系代词 提醒: 介词﹢关系代词引导的定语从句, 关键 是判断介词的选择. 方法一:根据从句中动词与先行词习惯搭配 方法二:根据从句中动词与先行词的逻辑关系 注意:关系代词在定语从句中作介词宾语时,从句常常由“介词+关系代词”引出。此时关系代词只能用which 或whom; 不可用that 或who 代替

(新)高中英语语法定语从句总结全

高中英语定语从句详解 Ⅰ. 概念: (1) 定语从句:在主从复合句中用作定语的从句叫定语从句。定语从句一般紧接在先行词(antecedent)后面。 (2) 先行词:被定语从句修饰的成份。先行词可以为一个词,短语,或整个主句。 (3) 引导定语从句的词叫关系词,分为关系代词和关系副词。 关系词的作用: 1) 引导定语从句,连接主句和从句,相当于一个连词; 2) 必在从句中作某个句子成份(可以做主语,宾语,表语,定语,状语) 常用的关系代词: that、which、who、whom、whose,当关系代词在定语从句中做宾语时,关系代词可以省略。 常用的关系副词(在从句中只作状语): when(时间状语)、why(原因状语)、where(地点状语) 可以修饰人的关系代词:that, who, whom, whose 可以修饰事的关系代词:that, which, as, whose, The student who answered the question was John. I know the reason why he was so angry. The boy (whom) you are talking to is my brother. I'd like a room whose window faces the sea. 定语从句三步: 第一找出先行词; 第二看先行词在定语从句中的语法功能(做主语、宾语、表语或状语); 第三选择合适的关系词。 Ⅱ. 几个关系代词的基本用法: ●that: 可指人或物;在定语从句中作主语,宾语,表语。(指人时,相当于who 或whom;指物时,相当于which)(一般不用于非限制性定语从句; 不可置于介词后作宾语) 如: 1. A letter that/which is written in pencil is difficult to read. (主语) 2. Do you know the gentleman that/who spoke just now? 3. You can take anything ( that) you like. (宾语) 4. What is the question (that/which) they are talking about? 5. Here is the man ( who/whom/that ) you want to see. 6. She's no longer the girl ( that) she used to be before.(表语) 7. Our hometown is no longer the one (that) it used to be. (= Our hometown is not the same as it used to be. = Our hometown is different from what it used to be。 = Our hometown is not what it used to be.) ●which: 指物;在定语从句中作主语,宾语。如: 1. The book which/that was on the desk was bought by my father.(主语) 2. The book (which/that) I bought yesterday is very interesting.(宾语) ●who, whom, whose: who: 主格, 在从句中作主语,只可指人 whom: 宾格,在从句中只能作宾语; 只可指人 whose: 表所属关系,在从句中作定语。译为:某人的,某物的

高考英语定语从句常见考点归纳

高考英语定语从句常见考点归纳 定语从句是中学英语教学的重点,也是学生学习的难点,同时又是高考考查的热点。纵观近年各地高考试题,就能发现考点大多集中在带有"插入语"的定语从句;which 、as 引导的非限定性定语从句;where 、when引导的定语从句以及定语从句和强调句、同位语从句的区别等方面。 对定语从句的考查不单纯考查其语法结构,而是把它融入到一定的语境中,考查考生的实际综合运用能力。 高考试题中,主要从以下角度考查定语从句: 定语从句的考点之一 that用法 正确区分关系代词that引出的定语从句功能强,除不能作定语(用whose)外,其它几个功能都可用that。但命题角度主要以that与which指物时的区别为重点进行命制。例如: (1)——Do you have anything in mind _________ you’d like for supper? ——Well, _________ is OK with me. A. that ; anything B. which ; everything C. what ; whatever D. where ; something 选A。 (2)The wrong you've done him is terrible, for ______ you should make an apology to him, I think. A. this B. which C. what D. that 选B。 定语从句的考点之二 判断成分,是关系代词还是关系副词 正确区分关系代词(that或which)与关系副词when(表时间)、where(表地点)、why(表原因)。 重点根据定语从句中所缺成分 (即关系词在定语从句中作状语时,使用关系副词when (on which); where(in which); why(for which);在定语从句中作作主语、宾语或表语时,使用that或which。)来确定是用关系代词还是关系副词,绝不能因先行词是时间名词就用when,是地点名词就用where,是reason就用why来确定。 因此,认准先行词只是选择关系词的一个方面,更重要的是看其在后面定语从句中充当什么句子成分例如: (3)He should stand near the stage ________ he could watch and follow the play. A. where B. when C. that D. there 选A。 (4)Do you think the reason _______ he gave is believable. A. for which B. which C. why D. what 选B。 (5)We are living in an age _______ many things are done on computer. A. which B. that C. whose D. when 选D。

定语从句用法归纳 篇一:定语从句的用法一、定语从句的有关概念所谓定语从句,就是在复合句中起定语作用以修饰主句中的名词或代词的从句。学习定语从句,首先要弄清两个重要概念——先行词和关系词。先行词是我们汉语中从来没有听过的一个新概念,它其实指的就是被定语从句所修饰的词。由于定语从句修饰名词或代词时,定语从句通常是后置的,所以人们就将放在定语从句前被定语从句修饰的名词或代词叫先行词。 那什么是关系词呢其实它就是用于引导定语从句的引导词。事实上,英语中的各类从句,不管性质如何,它们都需要有一个词来“引导”,正如人们给引导状语从句的词语取了个名字叫从属连词一样,人们也给引导定语从句的词语取了个名字,叫它关系词,因为它通常被放在先行词和定语从句之间起连接作用,以表明两者之间的修饰关系,同时它还在定语从句中充当一定的句子成分。二、定语从句中关系词与所修饰先行词的关系 为了更好地理解定语从句,我们还有必要研究一下关系词与先行词之间的关系。但在研究这种关系之前,我们先来看看关系词有哪些。根据关系词在定语从句中的作用,我们可以将关系词分为关系代词和关系副词两种。所谓关系代词就是指起代词作用的关系词,它们在引导定语从句的同时,还在定语从句中充当主语、宾语、宾语等,英语中比较常用的关系代词有that, which, who, whom, whose等。类似地,关系副词就是指起副词作用的关系词,它们在引导定语从句的同时,还在定语从句中充当状语等,英语中比较常用的关系副词只有三个,即when, where和why。许多初学定语从句的人弄不清关系词与先行词之间到底是什么关系。其实啊,关系词与先行词之间的关系很简单,简单得可以划一个等号。因为,关系词的含义在本质上等价于先行词,它与先行词指的就是同一个人或同一个事物。为便于理解,下面我们来看几个例子吧。I know the man who lives next door. 我认识住在隔壁的那个人。这是一个含有定语从句的复合句。句中的the man为先行词,who lives next door为修饰the man的定语从句;在定语从句中,who是关系词,它在定语从句中用作主语,从意义上说,它在

初中定语从句语法汇总

初中定语从句语法汇总 一、定语从句的基本概念: 定语从句即在句中有一个具有主谓结构的完整的句子来充当定语,修饰前面的名词短语或者代词。被定语从句修饰的词叫做先行词,定语从句必须放在先行词之后。引导定语从句的关联词有关系代词和关系副词。例如: This is the present that he gave me for my birthday. Do you know everybody who came to the party? I still remember the night when I first came to the village. This is the place where Lily once lived. 二、定语从句的分类 根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。 三、关系代词和关系副词的功用 关系代词和关系副词用来引导定于从句,在先行词和定语从句之间起纽带作用,使二者联系起来。关系代词和关系副词又在定语从句中充当一个成分。关系代词可以做主语,宾语,定语,关系副词可作状语。 1.关系代词:主要有that, which, who, whom, whose等,它们在句子中可用作主语(如that, which, who等)、宾语(如that, which, whom等)和定语(如which, whose)。 例句:I found the book which I was looking for.我找到了我要找的书。(做宾语)S he is the woman whose car was stolen.她就是汽车被盗的那个女人。(做定语) She is the woman whom I gave the money to.她就是我给她钱的那位妇女。(做宾语)Is he the man that sells dogs? 他就是卖狗的人吗? (做主语) She is the girl who won the prize.她就是获奖的姑娘。(做主语) 注意:关系代词在定语从句中作主语时,从句的谓语动词的人称和数须和先行词一致。 2.关系副词:主要有where, when, why等,它们在句子中主要用作状语。 (1)when指时间,其先行词表示时间,在句中作时间状语。 This was the time when he arrived.这是他到达的时间。 (2)where指地点,其先行词表示地点,在句中作地点状语。例如: This is place where he works.这是他工作的地点。 (3)why指原因,其先行词是原因,起原因状语作用。例如: Nobody knows the reason why he is often late for school. 没人知道他为什么上学总迟到。 四、关系代词的用法 1. that既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如: Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语) The coat (that)I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语)2.which用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如: The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语) The film (which)we saw last night was wonderful.我们昨天晚上看的那部电影很好看。(作
